V8

Kollur to Pune you can take "Kollur - Kumta - Sirsi - Yellapur - Hubli - Pune". I traveled on this route and this is the fastest route. The roads are good all over.

For Pune to Jaipur - If you start from Pune around 5:00am then you can target Halol. You may also visit Statue of Unity on the way. For more details please check my recent Travelogue.
Halol to Jaipur can be done within a day. You may also explore Chittorgarh if you have time.
